The inventor of the Danish submarine Peter Madsen, who was convicted of the torture, sexual assault, murder and dismemberment of a Swedish journalist, appeared before an appeals court to fight against his life imprisonment.
The three-day session in the Eastern High Court in Copenhagen will not deal with the guilty verdict of April 25.
Madsen, 47, still denies murdering Kim Wall, 30, but accepted the verdict to move forward, according to his lawyer.
In Denmark, a term of life is, on average, 16 years, but can be extended if necessary.
Madsen, who claims that Ms. Wall accidentally died inside the submarine in August of 2017, wants a limited time sentence, not an indefinite term.
He confessed to having thrown his body parts into the Baltic Sea.
Dressed in a dark blazer, a black T-shirt and jeans, Madsen listened in silence while prosecutor Kristian Kirk read the April verdict to present the case.
Later he looked away when Kirk played a police video of the interior of his submarine UC3 Nautilus, which he said was the largest private submarine in the world.
The City Court of Copenhagen had unanimously ruled that Madsen had lured Wall into his homemade submarine with the promise of an interview.
The court ruled that the murder was sexually motivated and premeditated, with the prosecution using Madsen's shifting explanations against him and citing a court-ordered psychiatric report that described him as "emotionally impaired with serious lack of empathy, anger and guilt" and have "psychopathic tendencies". "
Madsen's lawyer, Betina Hald Engmark, said the prosecution's case was based on "undocumented lawsuits."
Clearly, she said, Madsen did something "horrible" by smashing Ms. Wall, but she said that she should only be sentenced for that, noting that the cause of death had never been established.
According to Danish law, the "indecent" handling of a corpse carries a maximum sentence of six months in prison.
Ms. Wall wrote for The New York Times, The Guardian and other publications.
She had reported from Haiti after the earthquake, among other places, and studied at the Sorbonne University in Paris, the London School of Economics and Columbia University in New York.
He embarked on the submarine on a sunny August afternoon last year to interview Madsen, the co-founder of a company that develops and builds manned spacecraft.
His remains were found in plastic bags on the seabed weeks later.
Madsen initially said he had dropped Ms Wall on an island in Copenhagen several hours after his underwater trip.
He then claimed that Ms. Wall had died as a result of a buildup of pressure inside the submarine.
He later changed this to say that the reporter accidentally died inside the boat when a hatch fell and hit her on the head.
